Qt5 移植到 licheepi zero

前言

下載地址：https://download.qt.io/archive/qt/5.9/5.9.1/single/qt-everywhere-opensource-src-5.9.1.tar.xz

wget https://download.qt.io/archive/qt/5.9/5.9.1/single/qt-everywhere-opensource-src-5.9.1.tar.xz

tar xf qt-everywhere-opensource-src-5.9.1.tar.xz    #這里解壓也需要30s左右，別以為死機了，，
cd qt-everywhere-opensource-src-5.9.1

一、準備作業

確保以下軟體已安裝，

sudo apt-get install xorg-dev libfontconfig1-dev \
libfreetype6-dev libx11-dev libxcursor-dev libxext-dev \
libxfixes-dev libxft-dev libxi-dev libxrandr-dev libxrender-dev

二、配置

1、 解壓源代碼 qt-everywhere-opensource-src-5.9.1.tar.gz，并進入源代碼檔案夾

tar xf qt-everywhere-opensource-src-5.9.1.tar.xz    #這里解壓也需要30s左右，別以為死機了，，
cd qt-everywhere-opensource-src-5.9.1

2、指定所用平臺的 arm 架構以及交叉編譯器：

vim qtbase/mkspecs/linux-arm-gnueabi-g++/qmake.conf

改成以下內容，實際應需要根據自己的開發環境作出相應改變：

#
# qmake configuration for building with arm-linux-gnueabi-g++
#

MAKEFILE_GENERATOR      = UNIX
CONFIG                 += incremental
QMAKE_INCREMENTAL_STYLE = sublib

QT_QPA_DEFAULT_PLATFORM = linuxfb
QMAKE_CFLAGS_RELEASE   += -O2 -march=armv7-a
QMAKE_CXXFLAGS_RELEASE += -O2 -march=armv7-a

include(../common/linux.conf)
include(../common/gcc-base-unix.conf)
include(../common/g++-unix.conf)

QMAKE_INCDIR += /opt/tslib/include
QMAKE_LIBDIR += /opt/tslib/lib

# modifications to g++.conf
QMAKE_CC                = /usr/local/arm/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc -lts
QMAKE_CXX               = /usr/local/arm/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-g++ -lts
QMAKE_LINK              = /usr/local/arm/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-g++ -lts
QMAKE_LINK_SHLIB        = /usr/local/arm/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-g++ -lts

# modifications to linux.conf
QMAKE_AR                = /usr/local/arm/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-ar cqs
QMAKE_OBJCOPY           = /usr/local/arm/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-objcopy
QMAKE_NM                = /usr/local/arm/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-nm -P
QMAKE_STRIP             = /usr/local/arm/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-strip
load(qt_config)

心路歷程
?就必須得詳細的說交叉編譯工具在哪里吧！

3、根據自己的實際需求配置 Qt（此處是使用 tslib 的編譯）：
編輯一個檔案：vim cfg_arm.sh

#!/bin/sh
./configure \
-prefix /opt/qt5.9.1-arm \
-confirm-license \
-opensource \
-shared \
-release \
-make libs \
-xplatform linux-arm-gnueabi-g++ \
-optimized-qmake \
-pch \
-linuxfb \
-qt-libjpeg \
-qt-libpng \
-qt-zlib \
-tslib \
-no-opengl \
-no-sse2 \
-no-openssl \
-no-cups \
-no-glib \
-no-dbus \
-no-xcb \
-no-separate-debug-info \
-I/opt/tslib/include -L/opt/tslib/lib \
-nomake examples -nomake tools -nomake tests -no-iconv \
-tslib \
-I/opt/tslib/include \
-L/opt/tslib/lib \
-recheck-all

心路歷程

?開始配置的是 -make examples死活編譯出來，最后一個大佬提醒改成-nomake examples不管其他的，可算是編譯出來了！

三、編譯安裝

sudo make -j16
make install

安裝成功如下：

sudo make install 
......
/home/qt-everywhere-opensource-src-5.9.1/qtbase/bin/qmake -install qinstall /home/qt-everywhere-opensource-src-5.9.1/qttranslations/translations/qtxmlpatterns_pl.qm /opt/qt5.9.1-arm/translations/qtxmlpatterns_pl.qm
/home/qt-everywhere-opensource-src-5.9.1/qtbase/bin/qmake -install qinstall /home/qt-everywhere-opensource-src-5.9.1/qttranslations/translations/qtxmlpatterns_ru.qm /opt/qt5.9.1-arm/translations/qtxmlpatterns_ru.qm
/home/qt-everywhere-opensource-src-5.9.1/qtbase/bin/qmake -install qinstall /home/qt-everywhere-opensource-src-5.9.1/qttranslations/translations/qtxmlpatterns_sk.qm /opt/qt5.9.1-arm/translations/qtxmlpatterns_sk.qm
/home/qt-everywhere-opensource-src-5.9.1/qtbase/bin/qmake -install qinstall /home/qt-everywhere-opensource-src-5.9.1/qttranslations/translations/qtxmlpatterns_uk.qm /opt/qt5.9.1-arm/translations/qtxmlpatterns_uk.qm
make[2]: Leaving directory '/home/qt-everywhere-opensource-src-5.9.1/qttranslations/translations'
make[1]: Leaving directory '/home/qt-everywhere-opensource-src-5.9.1/qttranslations'
cd qtdoc/ && ( test -e Makefile || /home/qt-everywhere-opensource-src-5.9.1/qtbase/bin/qmake -o Makefile /home/qt-everywhere-opensource-src-5.9.1/qtdoc/qtdoc.pro ) && make -f Makefile install
make[1]: Entering directory '/home/qt-everywhere-opensource-src-5.9.1/qtdoc'
cd doc/ && ( test -e Makefile || /home/qt-everywhere-opensource-src-5.9.1/qtbase/bin/qmake -o Makefile /home/qt-everywhere-opensource-src-5.9.1/qtdoc/doc/doc.pro ) && make -f Makefile install
make[2]: Entering directory '/home/qt-everywhere-opensource-src-5.9.1/qtdoc/doc'
make[2]: Nothing to be done for 'install'.
make[2]: Leaving directory '/home/qt-everywhere-opensource-src-5.9.1/qtdoc/doc'
make[1]: Leaving directory '/home/qt-everywhere-opensource-src-5.9.1/qtdoc'

錯誤一：

dpaths_unix.o .obj/adler32.o .obj/compress.o .obj/crc32.o .obj/deflate.o .obj/gzclose.o .obj/gzlib.o .obj/gzread.o .obj/gzwrite.o .obj/infback.o .obj/inffast.o .obj/inflate.o .obj/inftrees.o .obj/trees.o .obj/uncompr.o .obj/zutil.o
make[3]: Leaving directory '/home/qt-everywhere-opensource-src-5.9.1/qtbase/src/tools/bootstrap'
make[2]: Leaving directory '/home/qt-everywhere-opensource-src-5.9.1/qtbase/src'
Makefile:48: recipe for target 'sub-src-make_first' failed
make[1]: *** [sub-src-make_first] Error 2
make[1]: Leaving directory '/home/qt-everywhere-opensource-src-5.9.1/qtbase'
Makefile:82: recipe for target 'module-qtbase-make_first' failed
make: *** [module-qtbase-make_first] Error 2

這個錯誤卡了好幾天，沒有法子！最后大佬提醒：
**configure 時加個 -nomake examples 引數，先不編譯examples看看能不能編譯過去
**

四、移植 Qt 到 licheepi 開發板

完成上述步驟后， qt5.9.1 將被安裝到/opt/qt5.9.1-arm 中，然后將安裝目錄/opt/qt5.9.1-arm全部復制到開發板的/opt/目錄中，將/opt/tslib中的 tslib目錄全部復制到開發板的/usr/local/中，

五、設定開發板 Qt 環境變數：

vi /etc/bash.bashrc

添加下面內容：

export TSLIB_CONSOLEDEVICE=none
export TSLIB_FBDEVICE=/dev/fb0
export TSLIB_TSDEVICE=/dev/input/event1
export TSLIB_CONFFILE=/usr/local/tslib/etc/ts.conf
export TSLIB_PLUGINDIR=/usr/local/tslib/lib/ts
export TSLIB_CALIBFILE=/etc/pointercal
export LD_LIBRARY_PATH=/lib:/usr/lib:/usr/local/tslib/lib:/opt/qt5.9.1-arm/lib
export PATH=/bin:/sbin:/usr/bin/:/usr/sbin:/usr/local/tslib/bin
export QT_QPA_PLATFORM_PLUGIN_PATH=/opt/qt5.9.1-arm/plugins
export QT_QPA_PLATFORM=linuxfb:tty=/dev/fb0
export QT_QPA_FONTDIR=/opt/qt5.9.1-arm/lib/fonts
export QT_QPA_GENERIC_PLUGINS=tslib:$TSLIB_TSDEVICE

保存退出后使上面的環境變數生效：

source /etc/bash.bashrc

在QtCreator上編譯好一個helloworld拷貝到開發板上去運行，–這里的重點就是需要配置安裝上面編譯好的目錄中的qmake否則是無法編譯成功的，
